I don't know! I have a buddy that uses piles of the stuff, but I've just gotten to like my large slew of powders so much that I've never given it a chance.

But I would assume that it meters much like Blue Dot and Green Dot which I do have... which is to say that my Lyman 55 does a fairly good job with them, but I know that I'm fortunate because many other measure really stink with these powders. My Hornady measure included.

To try Promo requires a bit of a leap of faith as it's 8 pounds or nothing... but you can snag those for typically under $90, so there's definitely a $$$ savings in there.
